Description

Technical Field

[0001] This utility model relates to the field of parboiled rice storage technology, and in particular to a dust-proof storage mechanism for parboiled rice. Background Technology

[0002] Parboiled rice, a semi-cooked rice product made through hydrothermal treatments such as cleaning, soaking, steaming, and drying, has inherent advantages such as complete nutrient retention, high yield, and good storage resistance. During processing, most microorganisms are killed and rice enzymes are inactivated, theoretically making it easier to store for longer periods than regular rice. However, in actual circulation, parboiled rice loses the original inner and outer husk protection of the paddy grain, with the endosperm directly exposed, making it susceptible to external environmental influences—especially in storage, where airborne dust easily adheres to the surface of the rice grains, causing contamination. As the grain industry upgrades towards green and intelligent practices, the market demand for integrated dust prevention, moisture control, and freshness preservation for parboiled rice storage is becoming increasingly urgent.

[0003] However, some existing devices use hot air for drying, but due to the agitator blades, they cannot cover the entire parboiled rice. Furthermore, if they do cover the entire storage tank, the resistance from the parboiled rice is too great, and the load on the rotating shaft is too heavy, which can easily cause damage. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art, and to propose a dust-proof storage mechanism for parboiled rice.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dustproof storage mechanism for parboiled rice includes a storage box with a cover plate on top. A rotating column is rotatably connected to the top of the cover plate. A cam is fixedly connected to the rotating column through the cover plate. A gear is driven by the rotating column. A gear plate meshes with the gear plate through the cover plate. The gear plate is rotatably connected to the cover plate. A second mounting block is fixedly connected to the side of the gear plate. A second spring is fixedly connected to one side of the second mounting block. A second hot air plate is fixedly connected to the end of the second spring away from the second mounting block. A first mounting block is fixedly connected to the side of the gear plate away from the second mounting block. A first spring is fixedly connected to one side of the first mounting block. A first hot air plate is fixedly connected to the end of the first spring away from the first mounting block.

[0006] The above technical solution further includes: The gear drive is connected to a belt, and the end of the belt away from the gear is connected to a rotating column. A valve is provided above the cover plate, and the valve has an air vent that communicates with the storage box.

[0007] A hot air blower is provided on the side of the toothed disc away from the cover plate, and the hot air blower is connected to the pipes of the first hot air plate and the second hot air plate.

[0008] The surface of the first hot air plate is provided with a humidity sensor for detecting the humidity of parboiled rice inside the storage box, and both the first and second hot air plates have holes for releasing hot air.

[0009] The gear plate is slidably connected to the first hot air plate, and the second hot air plate is slidably connected to the gear plate.

[0010] This sliding connection design can accommodate the reciprocating movement of the first and second hot air plates, allowing them to slide smoothly along the surface of the gear plate when the cam presses against them, preventing movement jamming caused by a fixed connection. At the same time, the sliding connection does not affect the driving effect of the gear plate on the two hot air plates when the gear plate rotates, ensuring that while achieving seamless stirring, detection, and drying, it also reduces hard friction between components, lowers mechanical wear, and improves the stability and service life of the mechanism.

[0011] A display screen is provided above the cover to show the number of dehumidification and drying cycles, and a sealing strip is provided between the cover and the storage box.

[0012] From a functional monitoring perspective, the display screen intuitively shows the number of dehumidification and drying cycles, allowing users to accurately grasp the processing status inside the storage box. The storage environment maintenance status of parboiled rice can be judged without disassembling the mechanism, improving operational convenience. From a dustproof and sealing perspective, the sealing strip fills the gap between the cover and the storage box, effectively preventing external dust from entering the box and contaminating the parboiled rice. At the same time, it reduces the leakage of hot air inside the box during the drying process, ensuring the efficiency of hot air utilization, further enhancing the dustproof and drying effects of the mechanism, and ensuring the quality of parboiled rice storage.

[0013] The surface of the toothed disc has a cut hole for the cam to rotate, and the side of the storage box has an electric valve for consuming parboiled rice.

[0014] For the cutting hole, it provides a dedicated rotation space for the cam, avoiding structural interference between the cam and the gear plate during rotation. This ensures that the two can work independently and smoothly under different transmission ratios, guaranteeing that the two functions of reciprocating the hot air plate and driving the hot air plate to rotate do not interfere with each other. For the electric valve, it replaces the traditional manual method of opening the lid to take out rice. Users can take out parboiled rice without opening the lid, which reduces the intrusion of external dust during the rice taking process and simplifies the operation process. At the same time, the electric control makes it easy to accurately control the amount of rice taken out, improving the practicality and convenience of the mechanism.

[0015] This utility model has the following beneficial effects: 1. In this utility model, in view of the problem that the existing device cannot cover all parboiled rice due to the fixed structure of the stirring blade, the mechanism drives the first hot air plate and the second hot air plate to rotate through the toothed disc. At the same time, the cam squeezes to make the two reciprocating dynamic displacements of moving away and moving closer. This movement mode, combined with the parboiled rice that can pass through the gaps on the surface of the hot air plate, can not only allow the hot air to penetrate into every corner of the storage box with the movement of the components, but also promote the flow of parboiled rice in the box, avoiding local accumulation and forming drying blind spots, and completely solving the problem of uneven drying caused by incomplete coverage of the stirring blade; 2. In this utility model, on the one hand, the gap between the surfaces of the first hot air plate and the second hot air plate allows some parboiled rice to pass through during stirring, directly reducing the frictional resistance between the components and the materials. On the other hand, the combined motion of rotation and reciprocating motion replaces the single rotation of the traditional stirring blade, dispersing the concentrated force of the material on the transmission system, significantly reducing the load pressure on rotating shaft components such as the rotating column, effectively avoiding damage caused by overload, and significantly improving the service life and operational stability of the equipment.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4As shown, this utility model is a dustproof storage mechanism for parboiled rice, including a storage box 1, a cover plate 2 on the top of the storage box 1, a rotating column 5 rotatably connected to the top of the cover plate 2, a cam 8 fixedly connected to the rotating column 5 through the cover plate 2, a gear 7 drivingly connected to the rotating column 5, a gear plate 16 meshing with the gear 7 through the cover plate 2, the gear plate 16 rotatably connected to the cover plate 2, a second mounting block 12 fixedly connected to the side of the gear plate 16, a second spring 13 fixedly connected to one side of the second mounting block 12, a second hot air plate 14 fixedly connected to the end of the second spring 13 away from the second mounting block 12, a first mounting block 9 fixedly connected to the side of the gear plate 16 away from the second mounting block 12, a first spring 10 fixedly connected to one side of the first mounting block 9, and a first hot air plate 11 fixedly connected to the end of the first spring 10 away from the first mounting block 9.

[0020] In one embodiment, for the gear 7, the gear 7 is driven by a belt 6, and the end of the belt 6 away from the gear 7 is driven by a rotating column 5. A valve 4 is provided above the cover plate 2, and an air outlet 18 communicating with the storage box 1 is provided inside the valve 4.

[0021] In one embodiment, for the aforementioned gear disc 16, a hot air blower 15 is provided on the side of the gear disc 16 away from the cover plate 2, and the hot air blower 15 is connected to the first hot air plate 11 and the second hot air plate 14 via pipes.

[0022] In one embodiment, the first hot air plate 11 is provided with a humidity sensor on its surface for detecting the humidity of parboiled rice inside the storage box 1, and both the first hot air plate 11 and the second hot air plate 14 have holes for releasing hot air.

[0023] In one embodiment, the gear disc 16 is slidably connected to the first hot air plate 11, and the second hot air plate 14 is slidably connected to the gear disc 16.

[0024] In this embodiment, the sliding connection design can adapt to the reciprocating moving distance and approaching movement requirements of the first hot air plate 11 and the second hot air plate 14. When the cam 8 presses the first hot air plate 11 and the second hot air plate 14, the two can slide smoothly along the surface of the toothed disc 16, avoiding movement jamming due to fixed connection. At the same time, the sliding connection does not affect the driving effect of the toothed disc 16 on the two hot air plates when rotating, ensuring that while achieving stirring, detection and drying without dead angles, hard friction between components is reduced, mechanical wear is reduced, and the stability and service life of the mechanism are improved.

[0025] In one embodiment, for the cover plate 2, a display screen 3 for displaying the number of dehumidification and drying cycles is provided above the cover plate 2, and a sealing strip is provided between the cover plate 2 and the storage box 1.

[0026] In this embodiment, from the perspective of functional monitoring, the display screen 3 intuitively presents the number of dehumidification and drying cycles, making it easy for users to accurately grasp the processing status inside the storage box 1. The storage environment maintenance status of parboiled rice can be judged without disassembling the mechanism, improving the ease of operation. From the perspective of dust prevention and sealing, the sealing strip fills the gap between the cover plate 2 and the storage box 1, effectively preventing external dust from entering the box and contaminating the parboiled rice. At the same time, it reduces the leakage of hot air inside the box during the drying process, ensuring the efficiency of hot air utilization, further enhancing the dust prevention and drying effect of the mechanism, and ensuring the storage quality of parboiled rice.

[0027] In one embodiment, the toothed disc 16 has a cut hole 17 on its surface for the cam 8 to rotate, and an electric valve for consuming parboiled rice is provided on the side of the storage box 1.

[0028] In this embodiment, the cut hole 17 provides a dedicated rotation space for the cam 8, preventing structural interference between the cam 8 and the gear plate 16 during rotation. This ensures that the two can work independently and smoothly under different transmission ratios, guaranteeing that the reciprocating motion of the hot air plate and the rotation of the hot air plate do not interfere with each other. As for the electric valve, it replaces the traditional manual method of opening the lid to take out rice. Users can take out parboiled rice without opening the lid 2, which reduces the intrusion of external dust during the rice taking process and simplifies the operation process. At the same time, the electric control makes it easy to accurately control the amount of rice taken out, improving the practicality and convenience of the mechanism.

[0029] The working principle of the dustproof storage mechanism for parboiled rice in this utility model is as follows: First, open the cover plate 2, then put parboiled rice into the storage box 1, and then close the cover plate 2. After a period of time, the rotating column 5 is rotated by controlling the rotation of the rotating column 5. The rotation of the rotating column 5 drives the gear 7 to rotate via the belt 6. The rotation of the gear 7 then drives the gear disk 16 to rotate. When the first hot air plate 11 and the second hot air plate 14 touch the cam 8, the first hot air plate 11 will squeeze the first spring 10 and move closer to the first mounting block 9. When the second hot air plate 14 touches the cam 8, it will squeeze the second spring 13 and move closer to the second mounting block 12. The transmission ratio of the gear 7 and the cam 8 is different. When the cam 8 rotates 1 revolution, the gear disk 16 has rotated 3 revolutions. Germicidal lamps and humidity sensors are set on the sides of the first hot air plate 11 and the second hot air plate 14. After a period of time, the gear 7 is controlled to mesh with the gear disk 16. Then, the rotation of the toothed disc 16 drives the first hot air plate 11 and the second hot air plate 14 to detect the humidity inside the storage box 1 and perform sterilization. When the humidity is significantly high, the hot air blower 15 is controlled and then delivers hot air into the first hot air plate 11 and the second hot air plate 14 through hoses. The hot air is then spread throughout the entire interior of the storage box 1 by the toothed disc 16. As the cam 8 rotates, it squeezes the first hot air plate 11 and the second hot air plate 14 respectively, causing the second hot air plate 14 to move away from and closer to the first hot air plate 11. This achieves overall sterilization and hot air introduction for drying inside the storage box 1. The hot air flows into the air through the air outlet 18. It is worth mentioning that the humidity can be observed several times during this period on the surface of the display screen 3. Furthermore, the stirring by the first hot air plate 11 and the second hot air plate 14 can achieve stirring without dead angles, thereby preventing the parboiled rice from sticking together due to high humidity.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
